'This program took on a life of its own starting from a basic mouse
'drawing program to then saving it as its own type of data file to
'then BMP pictures and now JPG pictures.
'Then other things were added such as rays, orbits, paint fill ins,
'boxes, printer support, Windows color picker, and editing.
'This program was made using QB64 and will always be Freeware.
'Paint PIxels was made by Kenneth G. with some help from
'the QB64 website Wiki pages.
'I want to thank the people who made and take care of the QB64 website
'and computer language. I have wanted to make a program like this for
'a very long time.
'It took 1 week to make this program and finished on June 5, 2019.
'Feel free to use any of its code below for your own creations but
'please don't copy more than half of it and sell it. Thank you.
'Just remember, there are much better graphics programs out there
'that can do much more than this can, but to me this is my pride and joy.
'One big thing I like a lot about this program is that it uses the
'entire computer screen to draw with. Also remember, I am no professional,
'just a guy who has loved BASIC programming for over 30 years.
'
'Technical Notes:
'This program uses around 55 MB RAM and 1% of the CPU on my semi-new computer.
'Use at your own risk. I hold no responsibility for any problems whatsoever.
'Here is the code needed for the Color Picker. The Function code
'is also at the end of this program.
